IMPROVEMENT IN VEHICLE-AXLE LUBRICATORS.

Specification forming part of Letters Patent No. 213,461, dated March 18, 1879; application filed September 2, 1878.

To all whom it may concern:

Be it known that I, JAMES M. SMITH, of Sycamore, in the county of De Kalb and State of Illinois, have invented a new and Improved Axle-Box, of which the following is a specifi- I cation:

The invention will first be described in connection with the drawings, and then pointed out in the claim.

In the accompanying drawings, Figure 1 is a longitudinal section of my improved axlehox and hub. Fig. 2 is a cross-section at the line 00 w, and Fig. 3 is a cross-section at the line 3 y, the packing being removed in the last two figures.

Similar letters of reference indicate corresponding parts.

a represents the journal of an axle. I) is the wooden hub, lined with a metal box, 0. The hub and wheel are retained upon the journal a by a nut, d, that is formed with a flange, e, that bears against the end of hub b. The inner face of the flange e is out out, or has an annular groove formed in it, into which fibrous material is packed, as seen at f.

The metal box 0 has one or more grooves, 9, cut in its surface lengthwise of the hub. These grooves g may be straight or spiral. The inner end of the box, where it comes next to the flange of the axle, is formed with an annular groove or cup, h. This cup h and the grooves g are filled with packing material.

iis a flan ge upon the journal a. It is cut out i at the side next the hub b, cup-shaped, as seen at k, and the space filled with packing material.

lis a perforated ring in the bottom of the space It, in front of an annular groove or space, m, that communicates with a passage, n, from the outside of the flange z. The passage n is covered by a turning plate, 0.

When the hub b is in place upon the axle, the packing in the space k of flange iand that in the cup h of the box 0 come contiguous, and are only separated by a perforated ring, 10,011 the journal at. This ring 1; is not, however, essential, as there may be direct contact between the surfaces.

Oil is to be poured in the passage 'n, and will saturate the material in the cup is, and from thence be communicated to the material in h, grooves g, and the packing at f. The axle may thus be oiled perfectly without removing the wheel from the axle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The perforated plate m, in combination with the recessed flange i and box 0, provided with grooves and recesses, filled with packing material, substantially as and for the purposes set forth.

JAMES M. SMITH.
